I implemented the transform which compiles out try/catch and throw blocks. The aim for the interpreter is to become a useful 'toy', very minimalist with an interactive mode for implementing small mathematical scripts.

The interpreter should be implemented excruciatingly simplistic.

The catch/throw compilation step is not entirely trivial and bites with a possible interactive mode. I need to think over how to implement the interactive mode upfront. I am too used to batch compiling things.
